You can use the terms "and" & "or" in your search; "or" phrases are resolved
first, then the "and" phrases. For example, searching for "black hole and
galaxy or universe" will find articles that have the phrase "black hole" in them
and also have either "galaxy" or "universe" in them. Please note that other
search syntax like quote marks, hyphens, etc. are not currently supported.

When you view web pages with matches to your search, the terms you searched for will be highlighted in yellow.

The FQXi podcast brings you the latest ideas in foundational physics and cosmology—and includes interviews with our members and other leading scientists. It's hosted by Zeeya Merali and Brendan Foster. You can contact us at podcast@fqxi.org, and follow us on twitter: @FQXi. The podcast is produced by Zeeya, and music is provided by Baltimore-based Diefenbaker.

Why Time Might Not Be an Illusion
Einstein’s relativity pushes physicists towards a picture of the universe as a block, in which the past, present, and future all exist on the same footing; but maybe that shift in thinking has gone too far.

The Complexity Conundrum
Resolving the black hole firewall paradox—by calculating what a real astronaut would compute at the black hole's edge.

Quantum Dream Time
Defining a ‘quantum clock’ and a 'quantum ruler' could help those attempting to unify physics—and solve the mystery of vanishing time.

Our Place in the Multiverse
Calculating the odds that intelligent observers arise in parallel universes—and working out what they might see.

Special edition of the podcast recorded at the Emergent Quantum Mechanics meeting in London.
Zeeya and Brendan chat to Nicolas Gisin, who argues that real numbers are not really real--and why that means that even classical physics is indeterministic, and the future is open. By contrast,
Emily Adlam makes the case for a deterministic 'Sudoku Universe.'
We have tips for the new essay contest, asking "What is Fundamental?"
FQXi and the Fetzer Franklin Fund launch a new large grant round, on Agency in the Physical World, as Anthony Aguirre and Jan Wallaczek explain.
And fine-tuning quantum theory, with Matt Leifer.

JIYA JOSEPH wrote on March 9, 2018In our school, we all might have learned real numbers and how it is used to solve the problems. Some students might have even thought why these real numbers are not real. There is no answer to such questions as we itself don’t know. chrome keeps crashing windows 10

LEE BLOOMQUIST wrote on February 8, 2018Edward Witten, in an interview with WIRED ___ https://www.wired.com/story/a-physicists-physicist-ponders-the-nature-of-reality/ ____ said "It from qubit" in natural language.

But a computer scientist would know that a software engineer versed in "formal specification languages"-- which are abstract programming tools used to specify what the real time programmers in assembly language should write-- might want to translate such a statement in natural language into an equation in a formal...

HANNAH BURREH wrote on February 1, 2018The real visible universe might only be more than a set of numbers - or we could also call it a simulation. The whole universe might not be "real" in general - but it is 100% real for us. Just like a computer program cannot escape its own reality in which it "lives" - the memory of a computer. Boundaries are yet to meet as we get to further technological advancements, so I hope we will soon come at least "closer" to the truth.
